Sea Floor Analysis

Creation Process:

• The map was created using GIS data from various sources including USGS, NASA, and NOAA. Hillshade, slope, and contour analysis techniques were applied in ArcGIS Pro to visualize the canyon's topography.

• Hillshade was generated to provide a 3D-like effect, highlighting terrain features with simulated lighting. Slope analysis was performed to show the gradient of the canyon walls, and contour lines were added to emphasize elevation changes.

Visual Details:

• The left panel shows a hillshade representation with varying shades of gray, where darker areas represent steeper and deeper parts of the canyon.

• The right panel uses a slope color scale, with shades of blue and purple indicating the steepness of the terrain.

• The lower panel contains contour lines representing elevation changes, helping to define the structure of the canyon floor and walls.

• A small inset map locates Norfolk Canyon along the U.S. east coast, and the map includes a legend with a scale bar and north arrow for orientation. The contrast between hillshade, slope, and contour provides a comprehensive view of the canyon's underwater topography.
